PennDOT says the bitter cold temperatures impact the effectiveness of road treatments, salt becomes less effective below 25 degrees and may not work at all below 15 degrees. Drivers should be aware of potential slick spots, especially in shaded areas and snow drifts.
And the department warns of ‘black ice,’ which can form on clear roadways, making roads look wet when they are actually icy. Extra caution is urged, especially on bridges and highway ramps. Visit www.511PA.com for up-to-date road info.
